My struts are getting really bad because the car will keep hopping on the left rear and experiences body sway. I wanted to know if it is possible to this kind of repair my self and some instructions.Do I need to get a left rear and Right Rear strut or does it really matter ? Also what tools do i need for the job ? I'm trying to reduce cost and pick up some repair skills at the same time. Appreciate the help guys.

We have no idea what your capabilities are. You have to determine what you can or can't do. Invest a small amount of money and buy a repair manual for your vehicle.
It will usually tell you if you need special tools or not. Most likely, if you have to ask if you can do it or not, then you probably shouldn't try it. Improper tools and procedure for this type of repair can get you hurt badly.

I would personally suggest that unless you are an experienced mechanic, don't try to replace struts on your own. I recently was having an issue with mine, brought it to the shop at the dealership I work at, and the repair man almost injured himself very badly because the strut mounting was worn away so much that the spring force (coil over shock) ripped the assembly off the car and basically threw itself at him. Luckily, he was standing to the side when it happened. He showed me the pieces that it broke into when he told me the story.
